Let's take a look at a frequency table. So, let's draw a table here. So, a frequency table gives you a certain piece of data. It tells you how many of those pieces you have. So let's say we're talking about, we've got a group of students in a room, and we want to know how many siblings they have. So this is number of siblings; so let's say somebody might have zero siblings - siblings means brothers or sisters, by the way. So let's say somebody might have 0, 1, 2, 3, 4 or even 5 siblings. Let's say that in this particular classroom, that's how many people, how many siblings somebody had. So this side is going to tell us the number of students in the room who satisfy that category. So let's say in this classroom there were three kids that had no other siblings; they were only children. There were two kids that had one sibling, three kids that had two siblings. There was one person who had three siblings, nobody had four siblings, and there was one person who had five siblings. This is called a frequency table. Sometimes it gives people a little trouble, because they're not sure what to make of these numbers. So this is the way we interpret it, once again: this tells me that, in this category of 0 siblings, 1, 2, 3, 4, or 5 siblings, that's the category, and this tells me the frequency - that's what that word means - or number of people in the room who fit that category. So three people had 0, two had 1, three had 2, 1. So if somebody, you were using this data table for homework and it said how many students in the room had 2 siblings, you'd look and say 3 students had 2 siblings. And that's the way you use the frequency table.
